They are priced at $431, if I recall correctly. This is a special price Steve (owner of Fullsac and fellow forum member), offers to us.
He is also a great guy to deal with. Do a search, and you'll find Fullsac and their products get nothing but good reviews. 
As North Star said Steve is a great guy to work with. I rode over from Phoenix to Lake Havasu, I met Steve at his shop he installed the X Pipe with the existing Rhinehart Slip Ons and the TTS, rode back that afternoon, bike ran great. I will have a week to get to check the exhaust out on the way back to Calgary via Pala and ride back through California.
I replaced an V&H Dresser Dual Head Pipe System, any one want to buy it. I also am installing a set of Carbon Filled Fuel Moto Slip ons. Now have the Rhinehart for sale.
